Abstract

A printed circuit board (PCB) including a first side and a second side; a conductive layer within the PCB between the first side and the second side; one or more first side electrical components that are physically attached to the first side and electrically connected to the conductive layer; one or more second side electrical components attached to the second side of the PCB and electrically connected to the conductive layer; and a thermally and electrically insulating dielectric layer, within the PCB between the first side electrical components and the second side electrical components, that prevents heat emitted by the first side electrical components from increasing the temperature of the second side electrical components.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A printed circuit board (PCB) comprising:
 a first side and a second side; 
 a conductive layer within the PCB between the first side and the second side; 
 one or more first side electrical components that are physically attached to the first side and electrically connected to the conductive layer; 
 one or more second side electrical components attached to the second side of the PCB and electrically connected to the conductive layer; and 
 a thermally and electrically insulating dielectric layer, within the PCB between the first side electrical components and the second side electrical components, that prevents heat emitted by the first side electrical components from increasing the temperature of the second side electrical components, wherein at least one of the first side electrical components vertically overlaps at least one of the second side electrical components. 
 
     
     
       2. The PCB recited in  claim 1 , wherein a top surface of the first side electrical component(s) is coplanar with the first side of the PCB. 
     
     
       3. The PCB recited in  claim 2 , further comprising a heat sink that directly abuts the first side and the top surface of the first side electrical components. 
     
     
       4. The PCB recited in  claim 1 , further comprising, an electrically-actuated turbocharger that receives the PCB within a PCB housing. 
     
     
       5. The PCB recited in  claim 4 , wherein the electrically-actuated turbocharger comprises a compressor and an exhaust turbine.
